The bridge rubber bearing is made of multilayer rubber sheet and thin steel plate. It has enough vertical steel to reliably transfer the reverse force of the upper structure to the pier; it has good elasticity to accommodate the rotation of the beam end and large shear deformation ability to meet the horizontal displacement of the upper structure.
The bridge rubber bearing not only has excellent technical performance, but also has the characteristics of simple structure, low price, easy replacement of cushioning and isolation without maintenance, and low building height. Therefore, it is quite popular and widely used in the bridge world.
Features: simple structure, low price, no maintenance
Scope of application: ordinary bridge rubber bearing is suitable for the span of less than 30 meters, small displacement of the bridge. Different plane shapes are suitable for different bridge spans, rectangular support for orthobridge, curved, diagonal and cylindrical piers.
